A scene from “Unfinished Business”

Valery Legasov took his own life at the age of 51 on April 26, 1988, exactly two years after the explosion at Chernobyl. The audio tapes of Legasov's memoirs were circulated among the Soviet scientific community. His suicide made it impossible for them to be ignored. In the aftermath of his death, Soviet officials finally acknowledged the design flaws of the RBMK nuclear reactors. Those reactors were immediately retrofitted to prevent an accident like Chernobyl from happening again.
